IMPROVEMENT IN Ronse-RAKES.

To ALL wHoM 1T MAY eoNcERN:

Be it known that I, Crans B. HOLDEN, of Worcester, inthe county of Worcester, and State of Massachu setts, have invented certain new and useful Improvements in Horse Hay-Rakes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specification, in whinhi f Figure 1 is a plan view of a hay-rake, made according to my invention.

Figure 2 is a vertical longitudinal section of the same,

Figure 3 is a transverse section also, on an enlarged scale, of one portion ofthe same'.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to that class of wheeled hay-rakes in which the rake-teeth are` tilted or lifted to discharge the hay in windrows by the traction of the apparatus, instead of by the employment of muscular force; and it consists in a tubular rake-head, formedof two parts. connected by a suitable yoke, and so oombined with the axle of tue supporting-wheels, and a ratchet and pawl, ns not only to provide for the requisite lifting-movement of the tines, but also to insure a very strong and durable construction of the rake. The invention further consists in certain novel means of insuring the more eiiicient operation of the mechanism employed in lifting o'r tilting the rake-teeth, of locking the rake-teeth in their lowered position during the operation of gathering the grass or hay thereon, of securely attaching the 'rake-teeth to the tubular head, and of providing for the convenient manipulation of the apparatus when in use.

To enable others to understand the construction and operation of my invention, I will proceed vto describe it with reference to the drawings.

The rake is formed with a cylindrical axle, A, provided with the two supporting-wheels B, one of which is firmly keyed or otherwise attached to the said axle, while the `other is loose thereon. Also attached to the' axle A is a. horizontal draught-frame, Ai, to which are aliixecl the tl'xills Atl, by which the rake is drawn.

C represents a tubular head, of 'cylindrical form, and the longitudinal bore of which is eccentric to the circumference thereof, as shown more fully in figs. 2 -and 3, and has passed through it the axleAyjust mentioned. The head C, instead of being formed ofone continuous piece, is made in two parts, the innermost ends of which are at some little space ap'art, as shown at a, and which are connected by a forwardly-extending yoke, b, as indicated in iig. 1. y

The eecentricform, just hereinbefore described, of the tubular head C, causes one side thereof to be much thicker than the other, so that holes may be lprovided transversely therein, as shown in iig. 3, in such manner that the inner ends a, of the wire teeth 0*, may be passed through and secured in such holes, 'the teeth being coiled one or more times around the aforesaid head, and having their main length or portion of any' ordinary or suitable form or curvature.

Attached to the axle in the space a, between the two parts of the tubular' head, is a ratchet, c, and pivoted to one side of 'the yoke b is a pawl, d, provided. with a weight, a', which operates to keep the puwl out of gear or contact with the ratchet c, except when the same is acted upon by the lever c, as hereinafter fully explained. The lever e is pivotcd at c to the lower part of a seniicircular vertical frame, B*, which extends from the 'axle at the space a, just hereinbefore mentioned, to the cross-bar ai, of the draught-frame A*,.the frame B* having provided upon it two studs, a b', which limit the vibratory movement of the lever. The lever e is'formed with a forwardly-extending arm, e, having at its extremity a weight, c', which tilts forward the lever, which furthermore has at one side a stud or pin.,b which extends over the pawl d, in such manner as to force such pawl into gear with the ratchet c, when the'levcr c is pulled buck. Extending downward from the lever e is a hook, f,which, when the lever is thrown forward by the weight c', catches under the front or forward part of the yoke b, and thus prevents the rising of the rake-teeth C* while gathering the hayv or grass, as hereinafter more fully explained. Provided upon the lower part of the frame Bl, and below the pawl ci, is a stud,f.

When the rake is drawn forward with the hook f', under the front of the yoke b, the teeth C* are prerentetl from tilting upward, and the grass 'or hay is gathered before` them, until it is desired to deposit the same in a windrow, whereupon the lever e is moved back, and presses the pawl d into gear or contact with the ratchet c.

AThe ratchet c, attached to the. axle rotatedbyV the wheel'B, firmly secured'thereto, being thus connected with the pawl d of the head C, carries the same around a portion of' a reirolution, thereby raising or tiltingvupward the teeth, and discharginglthe hay or grass therefrom. Bythe time this is done, the pawl d strikes the studf, which, by preventing its further movement in a downward direction, brings it clear from the ratchet-wheel c, thus enabling the teeth C* to'fall by their own weight to their rst position. When the lever e is released, it is brought forward to its original place by the weight e', with its hook,`f, catching underneath the front of the yoke l, to holdthe teeth in place while gathering the hay for the next windrow or-deposit, while the pawl d is kept clear of the ratchet c by means of its weight a', all as hereinbefore explained. What I claim as my invention, and desire tosecure by Letters Patent, is- 1'. The tubular head C, composed of two parts, connected by the yoke b, in combination with the axle A, the ratchet c, and pawl d, substantially as and for the purpose specied.

2. The arrangement ,and` combination of the hookf' and yoke b, with the tubular head C, and4 its teeth (2*, substantially as shown and described for the purpose set forth.

e 3. The tubular head C, arranged eccentrically upon the axle A, in such manner as to permit the innermost ends ofthe teeth C* to be passed throughsuch tubular head without interfering with the axle, substau tially as and for the purpose specified. y
